What really stuck in my head is the cowardly king. I can understand Jang Hyun's philosophy. I'm really curious about the relationship between those two; there seems to be something more than just a king and his subject.Jang Hyun remains the most courageous person in my eyes. Infiltrating the enemy and going to Ganhwa Island—it's incredibly brave. And Gil Chae is so witty; she's always the one saving their butts. Is it because she's the main lead? How is she always so alert and quick-thinking, as if she's been trained for it?
